The always_cow mode can't usefull preallocate space gіven that it
always has to write out of place, and thus will reject falloc or
ioctl calls to preallocate space in a file. Add explicit checks for
preallocation support in various XFS-specific tests to support this.

1) _require_fiemap and _require_xfs_io_command "fiemap" do the
same thing, but some test cases use the former and some use
the latter, so i feel they should be unified.
2) The number of helpers like this is slowly growing, but it's
easy to simply use _require_xfs_io_command directly and just
specify the command we want to check.
This is just a cleanup for keeping it simple.

Add a leading underscore to the get_block_size helper since it's a

For tests that only overwrite part of a file, only consider the number
of extents in the *rewritten* blocks when deciding if the FS
fragmentation performance is satisfactory.
(Also slip in a fix for xfs/127 so that it formats correctly when we
specify big blocksizes via MKFS_OPTIONS.)

This makes it clear when we are using "mount ; umount" versus "mount
-o remount" for most file systems. The reason for this distinction is
(a) tests may want to test the difference between what happens on the
remount versus the munt paths, (b) with tmpfs, "mount ; umount" will
cause the contents of all of the files to disappear which makes many
tests sad, and (c) some mount options may not be changed using "mount
-o remount".
Currently _scratch_mount performs "_scratch_mount ; _scratch_umount"
so mechnically rename this function to _scratch_cycle_mount. This was
done mechnically using the script fragment:
git grep "_scratch_remount" | \
awk -F: '{print $1}' | sort -u | \
xargs sed -i 's/_scratch_remount/_scratch_cycle_mount/g'
